After more than 40 years of law enforcement and security work so much horrific crime and hurt had been seen, much of which could have been avoided, I became " mad" and deeply concerned with the issues of safety, security and surveillance. This sparked a desire to start a business that can provide safety products that are safe, affordable and easy to use. Whether it be a pepper spray or a stun gun, a nanny cam for your child's safety, or a hidden or surveillance camera for your home or business; with over 600 products in which to choose, we are sure you will find the right products for your safety and security needs. We are proud to offer quality name brand products and to know that we can make a difference and save lives. DST was started in 2007.
